Harsh as in squeaky clean, or drying maybe? I've read of others who experience dryness after but I suspect that they may not be following with apple cider vinegar. Have you used it after the BS?

My hair seems to respond to BS well, even my face does. I've never tried anything based on aloe vera because I'm afraid of the protein (which all plant extracts have) but maybe I should try the combo on my face. Seems like whatever sends my face into panic mode does it also on my hair. And that last sentence really shows where my priorities are...lol.
